Abstract (en)

[origin: EP4135281A1] Provided are an industrial control system safety analysis method and apparatus, and a computer-readable medium. The industrial control system safety analysis method comprises: collecting a communication data packet from a first industrial control system, an operation technology (OT) network comprising the first industrial control system and at least one second industrial control system connected to one another, the communication data packet being interactive data transmitted between control devices in the first industrial control system; extracting network identifiable information from the communication data packet; determining whether the network identifiable information is located in a pre-created event database; and if the network identifiable information is located in the event database, then determining that the communication data packet is a malicious data packet, acquiring security policies of the first industrial control system and each second industrial control system, and determining a threat coefficient of the communication data packet for each second industrial control system according to the network identifiable information and each security policy. The present solution can analyze the safety of an industrial control system more accurately.
